To avoid possible electric shock and personal injury, please follow the following rules when using a multimeter:
1. Do not use damaged instruments. Before using the instrument, please check the instrument casing and pay attention to the insulation near the connecting socket.
2. Check the test leads to see if there is damaged insulation or exposed metal, check the continuity of the test leads, and replace the damaged test leads before using the meter.
3. Please do not use the instrument when operation is abnormal, so the protection may be damaged at this time. When in doubt, send the meter for repair.
4. Please do not use this instrument near explosive gas, steam or dust.
5. Please do not input more than the rated voltage marked on the meter between any two terminals or between any terminal and the ground.
6. Before use, please use the meter to measure a known voltage to verify the meter.
7. When measuring current, please turn off the power supply of the line before connecting the meter to the line.
8. When servicing the instrument, please use only the indicated replacement parts.
9. Please pay special attention when measuring AC voltage of 30V average, 42V peak or DC above 60V, because such voltages may cause electric shock hazards.
10. When using the test pen, please keep your fingers behind the hand of the test pen.
11. When measuring, please connect the public test lead (black test lead) first and then connect the live test lead (red test lead); when disconnecting, please disconnect the live test lead first and then disconnect the public test lead.
12. When opening the battery compartment, please remove all test leads from the meter.
13. Do not use the meter when the battery compartment or meter shell is not tightly closed or loosened.
14. When the battery low voltage indication symbol " " appears, please replace the battery as soon as possible to avoid possible electric shock or personal injury caused by false readings.
15. Please do not use a multimeter to measure voltages other than the CAT classification level shown on the multimeter.
